The US begins its official invasion of Iraq (see (7:40 a.m.) March 19, 2003). While most observers expect a traditional air assault, the US planners instead launch what they call a “Shock and Awe” combination of air and ground assaults designed to avoid direct confrontations with Iraqi military forces and instead destroy Iraqi military command structures. [CNN, 3/20/2003; CNN, 3/20/2003; Unger, 2007, pp. 302] The initial invasion force consists of 250,000 US forces augmented by 45,000 British troops and small contingents from Poland, Australia, and Denmark, elements of the so-called “coalition of the willing.” [BBC, 3/18/2003; Unger, 2007, pp. 302]
